This invention relates to a joint tting for the supporting pole oi a sun or other umbrella extensively used on beaches and in gardens, of the kind inrwhich a pair of hollow plugs, adapted to receive plugs are pivotally connected by the pin and nut Vll, E, the pin passing through concentric holes 6 in the inclined closed ends 3 so that the disposition of the pin il which is concealed is at right Having now described my invention, What I claim and desire to secure by Letters Patent is:

In a joint fitting for sun umbrella poles and the like, the combination with a pair of hollow plugs having terminal faces contacting with each other and being inclined at less than 45 to the axis of the plugs, a pivotal connection between said plugs one of said plugs having a peripheral ange of greater diameter than the plug, a sleeve embracing the last mentioned plug and having one end thereof in engagement With said flange,

means rigidly interconnecting said sleeve with its embraced plug, a second sleeve slidable o-ver the second plug and the edges of said terminal faces and into contact with said flange, and means associated with the movable sleeve and its plug to retain the sleeve in lowered position and embrace and hold said plugs alined, said movable sleeve being capable of being raised to permit the said plugs to be turned on their pivotal connection to inclined position.

THOMAS SIDNEY SMITH.
